Retirement Notes: Helton, Johnson, Oliver, Konerko

The season ended Sunday for 19 of baseball's 30 teams, many of which feature players who will not be back in 2014. Here are some notes on players whose careers might (or might not) be over.

Rockies great Todd Helton's illustrious career ended in Los Angeles, Thomas Harding of MLB.com reports. Dodgers broadcaster recorded a tribute to Helton that played on the scoreboard before the game, and he received a standing ovation for his last plate appearance. "The last at-bat, I got a little emotional, but other than that, it's Sept. 29th and I'm ready to go home," Helton says. Helton finishes his 17-year career with 369 home runs.

Veteran lefty Darren Oliver ended his two-decade career with a perfect inning for the Blue Jays on Sunday, MLB.com's Evan Peaslee reports. "20 years — very few guys get to do that," Jays manager John Gibbons says. "Longevity in this business is hard to come by, but to do it for that long and be that effective until the very end that speaks volumes." Oliver, 42, also pitched for the Cardinals, Red Sox, Rockies, Marlins, Astros, Mets and Angels, and he had three separate stints with the Rangers. He finishes his career with a 4.51 ERA, 5.9 K/9 and 3.4 BB/9 over 1,915 2/3 innings.

White Sox first baseman Paul Konerko still hasn't announced whether he's retiring, but he left Sunday's game against the Royals to applause, reports MLB.com's Scott Merkin. After a tough .245/.314/.356 season, it's unclear whether Konerko will be back, and if so, if that might be in a part-time role. Merkin notes that Konerko think for a month this offseason about whether or not to return in 2014. If he does want to return, the White Sox will have to decide whether to re-sign him.
